minutes) the root tip will feel soft when touched with a mounted needle (Do not let it dry out completely). * Heat it in order to speed up the process of the cell wall breaking down‚ and also for the stain to spread quicker. The stain will bind with the DNA‚ and it will become more visible. 4. Now‚ using forceps or the mounted needle‚ pick up the softened root tip and transfer it in to a

Date: May 22‚ 2012 Name: Cristhian Valor Organic Laboratory Pre-Lab 1. Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content

Starch is a mixture of two types of chain (amylose and amylopectin) formed from alpha-glucose. Amylose is formed when many alpha-glucose molecules condense together forming 1‚ 4 glycosdic bonds‚ so producing long unbranched chains. These chains take up a coiled or helical configuration as each monomer has a bulky side group which has to be accommodated. Amylose forms about 20% of starch. Amylopectin is branched and consist of alpha-glucose condensed together in two ways forming 1‚ 4 glycosidic bonds

Bio 205 Lab W/8:00 Enzyme II Write-Up Methods: My partner and I ran two experiments to measure the activity of the enzyme horseradish peroxidase under varied conditions. The first of which measured the effects of altered pH levels‚ while the goal of the second was to examine the effects of varied temperatures. To test the effects of pH on horseradish peroxidase‚ we began by zeroing a Spec 20 with 5.0mL of substrate (25mM guiacol) at pH 6.5. Once the Spec 20 was accurately zeroed‚ we added 100μL

Version 2: Identifying Dominant Plant Species 1- Hypothesis Based on the results‚ the bunchberry plant‚ with a scientific name of Cornus canadensis‚ was most frequently seen in station four‚ the ecotone‚ and second most in station five‚ the forest which is most likely in the lower forest since it has a similar environment to that of station four‚ and third most in station three‚ the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that

franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat
